[aklug] Re: Regarding terminal input

And of course.. python-serial, libdevice-serialport-perl or even using
ser2net to map a TCP/IP port to your serial port. If you have more
experiencing interfacing directly with network clients this could make
things easier.
I wrote a system back in the day for controlling robots using a Pontech
rs232 servo controller. It was written in python and used pyserial for
interfacing to the correct rs232 host device. It also ended up
implementing a very limited but speedy IRC/Channel like system. Input
was on certain channels, filters were listening to channels then
outputting requests to another channel which eventually hit the servo
controller.. It was a fun project. I'd love to have a happy little
robot to boss around again.
